Abstract:
Background: Early diagnosis of smear-negative and multidrug-resistant tuberculosis represents a national priority, considering the fact that the Republic
of Moldova ranks in the list of 30 high burden multidrug-resistance tuberculosis countries, with 26% rate of primary drug-resistance and 64% acquired
drug-resistance. In April 2012 it was implemented the real-time fully automated diagnostic molecular test in 15 Moldovan districts and penitentiary
institutions. The new assay leads to enhance the tuberculosis early diagnosis, especially multidrug resistant tuberculosis.
Material and methods: A retrospective, selective, descriptive and case-control study was performed using 361 new pulmonary tuberculosis patients,
diagnosed and hospitalized in the Municipal Clinical Hospital of Phthysiopneumology of Chisinau city in the period of 01.01.2014-01.01.2015. The
total sample was distributed in 2 groups: first group included 174 patients with pulmonary tuberculosis assessed by positive Xpert MTB/RIF assay and
the second group included 187 patients with pulmonary tuberculosis assessed having negative Xpert MTB/RIF assay. Investigations were performed
according to the National Clinical Protocols.
Results: The biggest rate of patients included in the research was detected by passive way, in the frame of examination of the symtomatic case: 111 (63.8%)
patients of the 1st Group comparing with 87 (46.5%) in the 2nd Group, p<0.001.
Conclusions: The use of Xpert MTB/RIF technique must be improved in municipality Chisinau for achieving the international quality standards.
